Offshore wind power jacket gravity-type cylinder-type infrastructure and construction method thereof

Abstract

The invention belongs to the technical field of offshore wind power, and discloses an offshore wind power jacket gravity-type cylinder-type infrastructure and a construction method thereof. The infrastructure comprises a reinforced concrete disc, a plurality of arc-shaped steel frames are mounted at the bottom edge of the reinforced concrete disc, and all subdivisions of the arc-shaped steel frames are provided with ventilating/water passing holes for being connected with a suction pump valve correspondingly; a jacket is mounted on the upper part of the reinforced concrete disc, the bottoms ofmain legs of the jacket are connected with subdivision cylinders correspondingly, and the subdivision cylinders and reserved groove holes of the reinforced concrete disc are connected through grouting; and the construction method of the offshore wind power jacket gravity-type cylinder-type infrastructure comprises the steps such as shore prefabrication, floating transportation consign voyage, step-by-step sinking, and grouting connection. The structural form is simple, land mass prefabrication can be achieved, the applicable water depth range is wide, the requirements for geological and terrain conditions are low, very high practicality is achieved, the mounting efficiency can be obviously improved, the mounting cost can be obviously lowered, and the fast, economical, convenient and quickoffshore wind power generator construction process is achieved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an offshore infrastructure structure and a construction method thereof. Background technique [0002] Wind energy and solar radiant energy are considered to be the most renewable resources that meet the requirements of human development. Among them, wind energy has the advantages of small environmental hazards, wide distribution of resources, suitable for local development, etc., and can be used on a large scale. The main form of utilization of wind resources is wind power generation, which is divided into two types: onshore wind power and offshore wind power. Among them, offshore wind turbines must not only bear huge wind loads, but also bear complex environmental loads such as waves and ocean currents. Therefore, the construction of offshore wind turbines, especially the construction of offshore wind turbine foundations, is much more difficult than onshore wind fa...
